APPARATUS FOR EXTRACTING ESSENCE.

SPECIFICATIOEI forming part of Letters Pazent No. 768,575, (ism-d August23, 1904.

T 0 all whom it Til/Ly wuwer'nf Be it'known that 1. Biznn E, HAM). acitizen of the United Eistes,.residing in the borough of Manhattan. on,county. andStute of New York, have Invented certain new and usefulImprovements in Apparatus for Extracting Essences, of which thefollowing is a specification.

'My invention relates to an apparatus for ext-ructingessences; and itconsists in the construction hereinafter described and claimed.

Intheacccmpanyungdrawmgsl have shownan essence-extractor embodying oneform of my invention.

in the draw ngs. Figure! 1511 horizontal sectional elevation of theextractor. is an end view of the still. and Fig. 111 is a section online III III of Fig. ll.

In the drawings. a indioutes asuitahle tunlt cnpnhleof withstanding highpressure. This tank is preferably mounted on a -suiuthlc foundation band is herein shown as having condensing devices consisting of a. domel' and a condenser-hood. A suitable valve apparatus I: may be employedfor the purpose .of-

controlling the flow of vapors into the condenser-hood.

Mou nted upon a suitable shaftfa nd located within the still is aforalninous or perforated drum g, preferably provided with a hingedTlI'ESlIRft-f DHSSQS portion 1:, forz niuga door. through a smiling-boxat one end of the stiil and is extended laterally to the left of theligure for some distance on the outside of the still. so as to permitthe drum to he removed from the still. the shaftfsliding in thestuffing-box 5. At the other end of the still I provide a removablehead. (More qlearly shown in Fig. II.) This removable head and itsfastening may be described as follows:

Rivcted or otherwise su itahly secured to the shell of the still I! is aring b. This ring is provided \vithan interrupted screw I. (ludi- Theupper face of the ring A is recesscdat "1, and a suit ahle packing-ringor gasket 1/ is preferably seated in the said annular recess.

Asuitable lip x is preferably formed on the head, which lip when thehead is in posit-ion will enter the recess in and hear upon the packingor gasket- 0. his packing or gasket; makes a tightjoint. which joint isin addition I to any joint that Piaf he formed by the interrupted screw.

The shaftf is preferably carried in bearings t, mounted ugam a suitabletruck or trev Ciil 'll. truck a source of motive power. (herein shown ofthe motor 1' to the shaftf of the still. I have also shown suitablestemn-inletpipes 1 2 and a waste-outlet pipe 3. It will be underdetailsI do not mean to limit myself thereto. i The mode of operation is asfollows: Let us suppose that the parts are in the position shown in'Fig. I of the drawings and that the revolving vlindez'orcage is withoutacharge The head of the still given a partial rota.- tiou, so as todiseugegetheinberrupted screw and joint, and the entirestructure istheresliding freely in the stuffing-box i at, the closed end of thestill. The charge is now the cylinder or cage run into thest-ill and thehead qresented again. Steam or other vapor or gas is new introducedthrough the pipes 1 or 2. or both of them. In the manui facture ofwitch-hazel the charge in the cage l is witch-hazel wood or brush. andthe fluid I medium employed for the distillation is steam. 114a: motor 1is started and the cage revolved, iso as to give thesteam an opportunityb0 i reach every part of the mass under treatment.
